Colipila, a new member of the Helotiales, is erected for two previously undescribed lignicolous species resembling Dasyscyphella and Lachnum by macroscopy. Species of Colipila are characterized by their long, entirely smooth, hyaline, thin-walled, multiseptate, subulate to basally fusoid hairs that tend to be curved on the stipe and lower flanks, and dimorphic, partly strongly protruding paraphyses which closely resemble the hairs. The type species, C. masduguana, is recorded repeatedly in southern France on rotten decorticated branches and trunks of Castanea sativa on the moist forest floor in sub-Mediterranean regions with siliceous soils, but also once on Quercus robur in a temperate forest with calcareous soil. The second species, C. pilatensis, was found on wood of an unidentified member of Rosaceae in a calcareous region of the Northern Alps and is known only from the holotype. The phylogenetic position of C. masduguana within the Helotiales was not resolved based on the analysis of nuclear LSU ribosomal DNA sequences. A key to the species of Colipila is provided. © 2011 German Mycological Society and Springer.

The genus Hyalorbilia in Macaronesia is reevaluated. Four species are new to this region (Hyalorbilia berberidis, H. brevistipitata, H. fusispora and H. polypori). Hyalorbilia inflatula is recircumscribed. The new combination Hyalorbilia polypori (Velen.) Baral & E.Weber is proposed. Hyalorbilia lunata is redefined according to vital taxonomy. A description of each species is given, together with notes on its distribution, ecology, and taxonomy. Similar species are briefly discussed. © 2014, J. Cramer in Gebr.

Lecophagus vermicola sp. nov. is described and illustrated as a predacious (carnivorous) hyphomycete living in bark fissures of living trees of Platanus and other angiosperm and gymnosperm trees, recorded in Hungary, Luxembourg and France. The fungus captures nematodes unlike other Lecophagus species, which are predators of rotifers and tardigrades. The morphology of the sessile, adhesive knobs differ from all previously described species of the genus which form adhesive pegs. Molecular data confirms that the new species belongs to the Lecophagus clade but without matching existing sequences. The fungus captures victims with adhesive knobs and colonizes its prey with a mycelium of rather broad hyphae on which, again, adhesive knobs are formed which penetrate the cuticule of the victim. Clusters of colonized nematodes form a network utilized to capture more prey. The fungus lives in the xeric, ephemerally aquatic habitat of bark fissures of standing, living or dead, corticated trunks and branches. The genus Haptocara is compared, which has similar adhesive knobs capturing nematodes and similar broad hyphae, but for which no molecular data was available. © 2016 German Mycological Society and Springer-Verlag Berlin Heidelberg

Xerombrophila, a new member of the Helotiales, is erected for a previously undescribed species that macroscopically resembles genera such as Phaeohelotium or Pezicula. The new species, for which we propose the name X. crystallifera, is characterized by a strong gelatinization of the medullary excipulum as well as the covering layer of the ectal excipulum, by the presence of abundant octahedral crystals, asci with an euamyloid apical ring that resembles the Calycina-type, and paraphyses containing refractive vacuoles. It can also be distinguished from members of both Ombrophila and Phaeohelotium in that it is desiccation-tolerant by surviving several weeks in the dry state. The species appears to be confined to xeric bark of Salix and was exclusively found over waterlogged soil, irrespective of being acidic or calcareous. It is known from various planar and colline areas of temperate Europe, and can be found throughout the year. Phylogenetic analysis of partial LSU sequences positions X. crystallifera as a sister taxon of a clade within the Helotiaceae s.l. that includes Ascocoryne, Chloroscypha, Gelatinodiscus, Neobulgaria and "Sarcoleotia" turficola. © 2012 German Mycological Society and Springer.

Recent molecular analyses separate Hymenoscyphus pseudoalbidus (causal agent of ash dieback in Europe) from the morphologically scarcely distinguishable H. albidus. Hymenoscyphus albidus was reported (as "Lambertella albida") on petioles of Fraxinus mandshurica in Japan. Phylogenetic analysis in the present study shows Japanese "L. albida" to be conspecific with H. pseudoalbidus but with a higher genetic variability compared to European isolates. The presence of croziers at the ascus base was found to be a clear distinguishing character of H. pseudoalbidus. Our phylogenetic analysis of the combined ITS and LSU-D1/D2 dataset supports Hymenoscyphus as more appropriate than Lambertella for H. pseudoalbidus. As the Hymenoscyphus clade includes members with two major characters (presence of substratal stroma and brown ascospores) currently used to circumscribe Lambertella, the generic delimitation of Lambertella requires redefinition. © 2012.

Helkogonium fusisporum, an intrahymenial ascomycete that forms its ascogenous hyphae and asci in the hymenium of Orbilia eucalypti (= O. coccinella s. auct. = O. alnea), is illustrated and described as a new species from Lithuania. © 2010. Mycotaxon, Ltd.

A new species of Orbilia related to O. luteorubella is described mainly based on morphological characters of its asexual morph and molecular data. The sexual morph does not significantly differ from O. luteorubella, whereas the asexual morph obtained from its ascospore isolate resembles members of the non-predacious genus Dactylella, because it has fusiform phragmoconidia borne singly at the apex of conidiophores. Phylogenetic analysis showed that this strain clustered with a clade that included available strains of the O. luteorubella aggregate and was distant from all analysed Dactylella species. Within this clade, the new strain fell between species with filiform conidia and those of a Pseudotripoconidium anamorph. By combining morphological and phylogenetic analyses, we conclude that our isolate belongs to a new taxon. Pleomorphism of the new taxon is described and discussed.
